Template synthesis and photochromism of a layered zinc diphosphonate

A zinc diphosphonate with protonated 2,4,6-tri(4-pyridyl)-1,3,5-triazine (H3TPT) as the template was hydrothermally prepared. The host layered framework was composed of 1-hydroxyethylidenediphosphonate and zinc ions. The guest H3TPT locates between the adjacent layers, acting as the charge balancer and template. The title compound features rapid photochromism upon irradiation with sunlight or UV light at ambient temperature.

Ligand-oriented assembly of a porous metal–organic framework by [CuI4I4] clusters and paddle-wheel [CuII2(COO)4(H2O)2] subunits

A novel porous mixed-valence copper–organic framework based on CuI4I4 clusters and paddle-wheel [CuII2(COO)4(H2O)2] moieties was synthesized through a ligand-oriented assembly. The mixed-valence Cu(I)–Cu(II) complex features the coexistence of micro-sized cages and 1D channels and its sorption behaviour has been investigated.
